Abstract: A pressure sealed chamber (15) such as load lock or processing chamber of an apparatus for processing substrates is operated with a guide plate (30) spaced from a substrate (20) supported in the chamber to form a gap (31) that covers the substrate surface (28) to be protected from contamination by moisture (27a) condensing in the chamber during the rapid evacuation thereof or particulates (27) picked up by the gaz during turbulent flow into or out of the chamber. During the evacuation of the chamber, by either pumping or venting, clean dry gas is introduced through an orifice (35) in the center of the plate so as to flow outwardly from the edge of the gap at a pressure sufficient to displace or otherwise prevent gas borne moisture condensate and particulates in the chamber from entering the gap and contaminating the surface to be protected of the substrate. During evacuation of the chamber, gas is introduced through the gap at a flow rate less that of the evacuating gas. During filling of the chamber, at least some of the filling clean gas is introduced through the orifice in the plate at a sufficient rate to prevent gas borne particulates from entering the gap.

Abstract: The invention relates to hose piping (17) having a plurality of parallel hoses (23) which can be wound onto a drum (20), as is used, for example, for supplying/scavenging a diaphragm wall milling tool or a similar underground-working tool. The problem exists in this case that no tension or compression may be exerted via this hose piping (17) on the apparatus which is suspended on a load cable since, otherwise, the apparatus would receive an undesirable lateral deflection. In addition, the hoses (23) must not be crushed during winding onto a drum (20). According to the invention, the hoses (23) are therefore connected to one another at predetermined longitudinal intervals by lateral webs (25) which hold the hoses (23) at predetermined lateral distances from one another. The lateral webs (25) are connected to one another in two strands (8), in a manner which is resistant to tension and is articulated, via spacers (26). During winding onto the drum (20), the spacers (26) come to rest on one another. In other respects, they are dimensioned such that the hoses (23) come to rest on one another in an unstressed manner in the individual layers. <IMAGE>

Abstract: 2.1 Known filters for separating out solids from the exhaust gases of an auto-igniting internal combustion engine, where the filter can be regenerated by burning off the deposited solids and the burning-off process can be initiated by electrical heating of the filter, have the disadvantage that at least under certain operating conditions, only incomplete burning-off of solids is achieved. This is due to the fact that the solids deposit on the filter upstream of the electrical heating in the flow direction and these layers deposited upstream in particular in the case of exhaust gas flowing through the filter during the regeneration process are insufficiently heated for initiating the burning-off process. 2.2 According to the invention, the filter is heterogeneously constructed, divided into a coarse-pore layer 1 and a fine-pore layer 2, the exhaust gas initially flowing through the coarse-pore layer 1 before the solids are separated out from the exhaust gas stream by the fine-pore layer 2. At the same time, the coarse-pore layer 1 is designed to be electrically conducting, so that during a regeneration process, complete burning-off of solids is ensured. <IMAGE>

Abstract: Apparatus and methods for delivering an amount of aerosolized medicine for inspiration by a patient in response to the occurrence of appropriate delivery point or points in the patient's detected breath flow. The aerosol medication may be administered as one or more pulses having a pulse width, shape, and frequency that will maximize the respirable fraction of the aerosolized compound being administered. The delivery point or points may be predetermined or determined from a prior inspiratory flow for depositing the selected medication at one or more desired locations in the patient's airway. Determined delivery points are recursively lowered for each inspiratory flow that does not satisfy one of the predetermined and previously lowered threshold. Changes in the patient's breath flow patterns during the course of an aerosolized medication inspiration therapy program may be detected and used to adjust the controlled amount of medication to be delivered in a given administration and/or to inform the patient of the patient's condition or change in condition. The device also may contain a library of administration protocols or operating parameters for different medications and a means for identifying from the canister the medicinal contents of the canister for customizing operation of the apparatus.

Abstract: The invention relates to a device for mounting or taking down a curtain from a rail, the curtain having suspending elements with T-shaped sliding heads and the rail possessing, on its underside, a guide slot running in the longitudinal direction of the rail and intended for guiding through the suspending elements. The sliding heads are pivotable through 90@ against spring action and can then come out of the guide slot of the rail. A hang-up magazine with an entry channel for the suspending elements can be attached in the region of the guide slot. The hang-up magazine additionally has a control curve with a narrowing, such that the sliding heads of the entering suspending elements are turned through 90@ via a cam and can thus be transferred from the rail to the hang-up magazine, in which process the suspending elements are securely guided by guiding flanges in a guiding curve of the hang-up magazine. The hang-up magazine furthermore possesses a flexible magazine bar which eventually receives all suspending elements, so that the curtain in question can be taken out of the rail or conversely introduced into it again. The hang-up magazine can be folded up by virtue of the flexible magazine bar to form a package which is suitable for passing through openings of washing machines, with the result that the curtain can be washed together with the hang-up magazine. <IMAGE>

Abstract: The VTOL aircraft includes a free wing having wings on opposite sides of the fuselage connected to one another for joint free rotation and for differential pitch settings under pilot, computer or remote control. On vertical launch, pitch, yaw and roll control is effected by the elevators, rudder and the differential pitch settings of the wings, respectively. At launch, the elevator pitches the fuselage nose downwardly to alter the thrust vector and provide horizontal speed to the aircraft whereby the free wing freely rotates relative to the fuselage into a generally horizontal orientation to provide lift during horizontal flight. Transition from horizontal to vertical flight is achieved by the reverse process and tile aircraft may be gently recovered in or on a resilient surface such as a net.
